With this new change, we propagate any original exception that was registered on the `Http2Connection` thus allowing any special handling of that original exception type before it gets propagated to the application code. Did I understand this correctly?

@jaikiran, thanks so much for the review, much appreciated! 🙇 As discussed with you and @dfuch,

- Changed the ticket labels to `httpclient` and `intermittent`
- Added the JBS issue ID to the `@bug` list of `AsyncExecutorShutdown`
- Wrapped the `cause` in an `IOException` in `putStream()`
